تعريف nitric oxide في الإنجليزية الإنجليزية القاموس.: the binary compound of nitrogen and oxygen NO; an unstable compound which rapidly oxidizes in the presence of air; A colorless, poisonous gas, NO, produced as an intermediate during the manufacture of nitric acid from ammonia or atmospheric nitrogen and as a product of cellular metabolism. In the body, nitric oxide is involved in oxygen transport to the tissues, the transmission of nerve impulses, and other physiological activities. Colourless, toxic gas (NO), formed from nitrogen and oxygen by the action of electric sparks or high temperatures or, more conveniently, by the action of dilute nitric acid on copper or mercury. First prepared 1620 by Jan B. Helmont, it was first studied in 1772 by Joseph Priestley, who called it "nitrous air." An industrial procedure for the manufacture of hydroxylamine is based on the reaction of nitric oxide with hydrogen in the presence of a catalyst. The formation of nitric oxide from nitric acid and mercury is applied in a volumetric method of analysis for nitric acid or its salts. The gas is synthesized via enzyme-catalyzed reactions in humans and other animals, where it serves as a signaling molecule. Among its numerous biological roles, it causes dilation of blood vessels and as such is an important regulator of blood pressure. Nitric oxide is one of the components of air pollution generated by internal-combustion engines; A potent vasodilator, NO is released by endothelial cells, signaling smooth muscle cells to relax Nitrates and nitrites mediate their pharmacological effects by releasing NO Press the "back" button to return to where you came from; A gas formed by combustion under high temperature and high pressure in an internal combustion engine; it is converted by sunlight and photochemical processes in ambient air to nitrogen oxide NO is a precursor of ground-level ozone pollution, or smog; A gas formed by combustion under high temperature and high pressure in an internal combustion engine; changes into nitrogen dioxide in the ambient air and contributes to photochemical smog; a poisonous red-brown gas (NO); A gas formed by combustion under high temperature and high pressure in an internal combustion engine It changes into nitrogen dioxide in the ambient air and contributes to photochemical smog; A gas produced by bacterial action in the soil and by high temperature combustion Nitrogen oxide is a component in the production of photochemical smog This colorless gas has the chemical formula is NO; A gas formed in great part from atmospheric nitrogen and oxygen when combustion takes place under high temperature and high pressure Not in itself a pollutant, in the ambient air NO converts to nitrogen dioxide, a major contributor to photochemical smog Also see photochemical smog; a reactive oxygen intermediate (free radical) that has several biological functions; A small, membrane-permeant molecule that is thought to serve as a cellular signal Nitric oxide (NO) is formed by the enzyme nitric oxide synthase from the amino acid arginine; (NO)-precursor of ozone, NO2, and nitrate; usually emitted from combustion processes Converted to nitrogen dioxide (NO2) in the atmosphere, it then becomes involved in the photochemical process and/or particulate formation; A gas formed by combustion under high temperature and pressure in an internal combustion engine It changes into nitrogen dioxide in the ambient air and contributes to photochemical smog Back to Top; chemical compound; a trace species that plays an important role in both tropospheric and stratospheric chemistry Natural sources of NO include emissions from microbes in soils, forest fires, and lightning discharges Unpolluted levels of NO are in the 0 01-0 05 ppb range, but emissions from high-temperature fuel combustion sources can increase levels by a factor of 1000 or greater, to 50-750 ppb in highly polluted areas NO is important in urban areas, where it can react with hydrocarbon species to form ozone and other secondary pollutants, which can jave negative health effects on humans and plants NO is also soluble in water, and contributes to acid rain (nitric acid) deposition In the stratosphere, NO is important in the catalytic destruction of ozone, and is very important in the series of events leading to polar ozone depletion during the Arctic and Antarctic springtime; chemical compound (formula NO) with vasodilatory properties; no-; no; nitrogen monoxide
